I have a Rodgers C-445 organ, using the Roland SK-7 keyboards, recently it exhibited some notes dropping out. The key contacts are rubber with graphite tips connecting to printed pattern on a flex pc board. Does anyone have a diagram of how to check the contacts with a continuity meter. Neither Rodgers or Roland (the manufacturer) have been much help. Roland will not even sell the rubber contact parts to individuals. I would appreciate any help anyone can offer.
